Upon reaching the rank of apprentice, I realized that you still can't do two of my favorite WE commands; setbiome and floodfill. I think it would be a good idea to allow for these, setbiome so that we can have sections of our plot that are different biomes from the rest, and floodfill for obvious reasons.
//setbiome can be substituted for /ap biome [name of biome]. Use /ap biomelist to get a list of the ones you can use
The problem with /ap biome is it sets the whole plot, not just part of the plot (which is what @Lord Arrani wants)
